Posting to a Google Forms form using NSURLRequest

Question

I am trying to post a string to a Google Form using NSURLRequest. The method seems to be getting called, but the post to the Google Form doesn't appear. This is the code I am using:

NSURL *requestURL = [NSURL URLWithString:@"https://docs.google.com/forms/d/1T9M6B_k4tiQcSPP5iS2jyU7DCkoRC1jFVql_eQDy9ek/formResponse"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:requestURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];
[request setHTTPMethod:@"POST"];
NSString *postString = @"entry.757751040=Test sent from iOS App";
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];

if (connection){
    NSLog(@"Connecting...");
}

I created this form solely for testing purposes. "Connecting..." gets logged, so I know the connection is being made, but the string does not appear in the Google Forms Spreadsheet. Am I doing something wrong? Any help would be greatly appreciated.

Answer 1

This piece of code only checks if connection is not nil

if (connection){
    NSLog(@"Connecting...");
}

is equivalent to

if (connection != nil){
    NSLog(@"Connecting...");
}

As such, it has nothing to do with an actual connection to the URL.

The method initWithRequest:(NSURLRequest *)request delegate:(id)delegate which you are using will perform the request immediately. This means that you have to perform the operations in another order if you want your params to work:

NSURL *requestURL = [NSURL URLWithString:@"https://docs.google.com/forms/d/1T9M6B_k4tiQcSPP5iS2jyU7DCkoRC1jFVql_eQDy9ek/formResponse"];
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:requestURL cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
[request setHTTPMethod:@"POST"];
NSString *postString = @"entry.757751040=Test sent from iOS App";
[request setHTTPBody:[postString dataUsingEncoding:NSUTF8StringEncoding]];
[request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"content-type"];
NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

Along with this, consider implementing NSURLConnectionDelegate.
